METAL WINDOW-SASH.

Patented Aug. 11, 1914.

i and PERCY L. BART-ER, citizens of the United States, residing atDetroit, in the county of -Wa-yne and State of Michigan, have inventedcertain new and useful Improvements in Metal Window-Sash; and we dohereby declare the following to be a full, clear, and exact descriptionof the invention, such as will enable others skilled in the art to whichit appertains to, make and use the same. 7

Our invention has for its object to provide an extremely simple andhighly eflicient 'metaljwindow'sash, especially designed for use in carconstruction, wherein combined strength and simplicity in the corner, ormiter, construction is very essential.

To the above end, generally stated, the invention consists of the HOW-51construction and arrangement of parts hereinafter described and' definedin the claims.

In the accompanying drawings, which illustrate the invention, likecharacters indicate like parts throughout the everal views.

Referring to the drawings :Figure 1 is a side elevation of the improvedwindow sash, some parts broken away, and some of the exposed parts shownin section. Fig. 2 1s an, oblique section taken on the line m m of Fig.1, on an enlarged scale. Fig. 3 is a detail view, principally insection, taken on the line 00 m of scale; and Fig. 4 is a detail view insection, showing the rail sections separated at one ofthe joints.

1 The numeral -1 indicates, as an entirety, a metal window sash havingits rail 2 made up of'v'ertical and horizontal flattened tubularsections, in rectangular arrangement, and connected by miter joints ofnovel construction which will presently be described. Each rail section2 is primarily open at its outer edge andis constructed from a-singlepiece of sheet metal which is first blanked and then bent to shape. Attheir inner edges, the rail sections 2 are bent to afford a seat 2 for aglass panel and a seat 2 for the glass panel securing means. Forthepurpose of this case, it is not thought necessary to illustrate eitherthe glass panel or its securing means.

At their ends, the sides of the rail sections 2 are bent laterallyinward to afford, at each end of the rail sections 2, a pair of over-Flg. 1, on an enlargedi lapped flanges 3 that are spaced apart, one fromthe other, a distance equal to the thickness, of the metal from whichthey are formed, 'as best shown in Fig. 4. In assembling the rail of thewindow sash, the abutting ends of the vertical and horizontal sectionsthereof are connected by interlapping the flanges 3, as best shown inFig. 3. This is done by bringing directly together all of the flanges 3on the same side of the rail and overlapping the flanges on one side ofthe rail with the flanges on the other side thereof.

At each miter. joint, the interlapped sectionsz2, at their miter joints,against twisting action.

After the rail sections 2 are securely joined together, the open outeredges thereof are permanently closed by a shoe 6. This shoe 6 ispreferably made channel shape in cross section,as shown,withitstransverse portion? spanning "the-"opening between the sides ofthe rail sections 2, and with its side flanges embracing the outerlongitudinal edges of the sides of the rail sections 2. The shoe 6 ispreferably secured to the rail sections 2 by sweating, and may beconstructed either-from asingle piece of metal bent rectangular, to fitaround the rail sec tions 2, or in a separate section for each railsection 2.

What w claim is 1. A metal window sash having a tubular rail, thesides-of said rail being bent'laterally inward, at their ends, to aflordoverlapping, laterally spaced flanges, the flanges on the same side ofsaid rail being brought directly together, the flanges on the one sidebeing overlapped with the flanges on the other side, and means securingthe same to- 'gether.

2.. A metal window sash having a tubular rail, the sides of said railbeing bent laterally inward, at their ends, to afford overlapping,laterally spaced flanges, the flanges on the same side of said railbeing brought directly together, the flanges on the one side beingoverlapped with the flanges on' the other side, and means securing thesame together, comprising clamping bars and bolts.

3. A metal window sash having tubular rail sections in rectangulararrangement, the sides of said rail sections being bent laterallyinward, at their ends, to afford overlapping, laterally s aced flanges,the flanges on the same sideo said rail sections being T. Y. J OSLYN, J.W. CAIN.
